LAMOST medium-resolution spectroscopic survey of binarity and exotic star (LAMOST-MRS-B): Observation strategy and target selection
Jiao Li, Jiang-Dan Li, Yan-Jun Guo +15
LAMOST-MRS-B is one of the sub-surveys of LAMOST medium-resolution (R~7500) spectroscopic survey. It aims at studying the statistical properties (e.g., binary fraction, orbital per…
The statistical properties of early-type stars from LAMOST DR8
Yanjun Guo, Chao Liu, Luqian Wang +5
Massive binary stars play a crucial role in many astrophysical fields. Investigating the statistical properties of massive binary stars is essential to trace the formation of massi…
Mass-Ratio Distribution of Binaries From the LAMOST-MRS Survey
Jiangdan Li, Jiao Li, Chao Liu +7
Binary evolution leads to the formation of important objects crucial to the development of astrophysics, but the statistical properties of binary populations are still poorly under…
Identification of new classical Be stars from the LAMOST MRS survey
Luqian Wang, Jiao Li, You Wu +6
Be stars are B-type main-sequence stars that display broad Balmer emission lines in their spectra. Identification of Be population is essential to further examine the formation and…
